安装tensorflow时遇到的问题即解决方法。
安装tensoflow前的准备
(通过pip安装，如果还没有安装pip的话，可以通过下面的命令安装pip)
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py sudo python get-pip.py
安装命令：
pip install tensorflow

解决方法
通过easy_install安装nose和tornado
sudo easy_install nose sudo easy_install tornado
升级setuptools到最近的版本
pip install --upgrade setuptools --user
这里使用了--user. 曾经尝试使用sudo pip install --upgrade setuptools, 但是失败。告知no permission.
sudo -H pip install --upgrade setuptools
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
